A fuel cell arrangement has at least one gas tight and liquid tight fuel cell casing (40) within which a cathode, an electrolyte and an anode of the fuel cell (1; 100) as well as flow channels for oxidant (18) and/or fuel gas (22) are arranged, and a device for regulating the operating temperature of the fuel cell, which comprises a heat exchanger container (34) which at least partially surrounds the fuel cell casing, with a heat transport medium (38) circulating in the heat exchanger container, and absorbing waste heat from the fuel cell, from the fuel cell casing that is used as a heat exchanger surface. This means that the heat transport medium flows around all of the fuel cell casing, which makes it possible to compensate for local temperature differences between individual fuel cells, in particular in the region in which the fuel gas is supplied. A plurality of fuel cells with one fuel cell casing are preferably arranged in a common heat exchanger container. The fuel cells are preferably tubular and have two end faces, a tubular wall extending between them and, in each case extending in the form of a casing therein, a cathode and an anode with a solid electrolyte between them, an inner flow channel for oxidant or fuel gas, and an outer flow channel, surrounding the tubular wall, for fuel gas or oxidant. |
